[experimental-tmp2] Add msm8956 Sony Loire (kugo & suzu)

[vknecht]

This is not booting yet (it reboots), so creating as draft for further discussion. Several this are still unclear to me:

• license : guess BSD-3-Clause is prefered, not sure if something warrants setting another
• lk2nd,match-cmdline : comparing one kugo & one suzu, about only differences are lcdid_adc and serial which begins with BH902H (kugo) or BH902F (suzu), so I choose lcdid_adc for now
• from chat discussion, it would seem something like b8f0b9d is needed to not hang wrt. cores/clusters. Setting would be the same as msm8939 so I guess it would be done by :
  • add APCS defines in platform/msm8952/include/platform/iomap.h (not exactly same as msm8916 ?)
  • create lk2nd/smp/clock-msm8952.c (probably not same as msm8916 ?) and add msm8952 at lk2nd/smp/rules.mk#L8 ?
  • add something in platform/msm8952/msm8952-clock.c ?
• in msm8953 fork, several devices need changing #address-cells / #size-cells, how to check if that's required for loire ?
• ...

Is doing device detection based on panel variation really reliable?

Is doing device detection based on panel variation really reliable?

To me these look like veeeery sony specific parameters that would probably work fine but I'm pretty concerned with the fact it says "adc" in the name which implies it would measure an analog value...

Change to match cmdline on (partial) serial number. Should work at least here for my tests, will check how "universal" that numbering rule is...

It boots now on kugo with latest change, but doesn't seem to be able to fastboot boot twrp (stuck on tux logo)

(bootloader) Staged. Use 'fastboot get_staged <file>' to fetch.
